Hi there,

We’ve an SSSP web app that we use in tizen for the last 4 years. It installs in models running tizen 2.3, 4 and 5 without any issues.

This week, a customer of ours bouth a display model QMC 32 24/7 apperently running Tizen 7 and the same install procedure as before downloads the app and in the end give an error message like “Can’t install application”.

Any idea why or which changes do I need to do to support Tizen 7?

Thanks in advance.

Hi there,

I’ve found that I needed to create a certificate using the Samsung distributor certificate. My older one was using the Tizen distributor certificate.

My problem now is that the Samsung distributor certificate required me to specify the device DUIs where the app will be used. Our app isn’t used in any Samsung or Tizen store. It’s installed directly in the screens.

How will I know which DUIs we’ll find in the future so the app can be install in any Tizen 7 devices? I’ll need to create a new certificate and build my app everything a new screen appears (to add the DUI).

Thanks for the help.

Same problem here. I was able to sign distribution packages (.wgt) using SDK CLI with a “dummy” self-generated certificates. I was doing that without providing device serial numbers and it worked on Tizens from 2.3 to 6.5. Those applications will not run on Tizen 7.0 now. Still looking for a solution.

I was able to install our app in Tizen 7 but I must create a Samsung Certificate and not a Tizen Certificate (which I used before in all devices).

The problem with the Samsung certificate it that it requires that you specify the device DUID. Only after you put the device unique id in the certificate you’ll succeeded installing the application. This is a pain for us because it means we’ll need to create an app for each device instalacion (because we can’t guess whih device ids we’ll find in the future).

Something is must be possible to do because I’ve installed the https://signagelive.com/ app in this screen and it installs without problems. They must be using something that allows them to install their app on any screen. I just don’t have a clue on how to do that.

Any help to better understand this will be appreciated.

Hello,
You can add multiple DUID manually during certificate creation.
Check step 4: Add individual DUIDs.

Still if you have any confusion or I misunderstood your issue, you can reach the TV support channel:
(Seller2.0) and submit a 1:1 QA in the Support Tab.

Thanks!

Hi there,

I know we can add multiple DUID.

The problem is if we have an app that’s installed in tizen devices how can we “guess” in advance which DUIDs we’ll find?

Also, I know there’s a 50 DUID limit to be added in each app. Which means that I’ll have to make a nw app for every new customer we get to add their DUIDs. Also, if one screen has a problem and needs to be replaced, we need to change our app to edit the certificate, add a new DUID for the new screen.

In every other tizen devices (apart from QMC) we didn’t need this. We could install our tizen app without this DUID thing…

Is there any way to “deal” with this? We’re a company that develops a signage / coorporate TV app which will never be published in any store and we use it in out customers screens only.

Thanks.
